Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018242, here are decompositions:
- 19 + 1018223 = 1018242
- 41 + 1018201 = 1018242
- 151 + 1018091 = 1018242
- 223 + 1018019 = 1018242
- 283 + 1017959 = 1018242
- 353 + 1017889 = 1018242
- 383 + 1017859 = 1018242
- 443 + 1017799 = 1018242
Showing the first eight; more decompositions exist.
